Q
Q: If log10(x) = -1, what is the value of x?
Solution:
x = 10^-1 = 0.1.
Steps: 5
Show Steps
Step 1: Understand that log10(x) means 'the power to which 10 must be raised to get x'.
Step 2: The equation log10(x) = -1 means that 10 must be raised to the power of -1 to get x.
Step 3: Rewrite the equation in exponential form: x = 10^(-1).
Step 4: Calculate 10^(-1), which is the same as 1 divided by 10.
Step 5: Therefore, x = 1/10 = 0.1.
